Expand description
quickjspp is a a Rust wrapper for QuickJSpp, a new Javascript engine by Fabrice Bellard.
It enables easy and straight-forward execution of modern Javascript from Rust.
Quickstart:
use quickjspp::{Context, JsValue};
let context = Context::new().unwrap();
// Eval.
let value = context.eval("1 + 2").unwrap();
assert_eq!(value, JsValue::Int(3));
let value = context.eval_as::<String>(" var x = 100 + 250; x.toString() ").unwrap();
assert_eq!(&value, "350");
// Callbacks.
context.add_callback("myCallback", |a: i32, b: i32| a + b).unwrap();
context.eval(r#"
// x will equal 30
var x = myCallback(10, 20);
"#).unwrap();Modules
- Javascript console integration. See the ConsoleBackend trait for more info.
- Serde integration.
Structs
- A wrapper around Vec
, used for vararg callbacks. - A value holding JavaScript BigInt type
- Context is a wrapper around a QuickJS Javascript context. It is the primary way to interact with the runtime.
- A builder for Context.
- Wraps a quickjs context.
- A bytecode compiled function.
- Wraps an object from the QuickJs runtime. Provides convenience property accessors.
- A bytecode compiled module.
- Wraps an object from the QuickJs runtime. Provides convenience property accessors.
- OwnedJsValue wraps a Javascript value owned by the QuickJs runtime.
Enums
- Error on context creation.
- Error on Javascript execution.
- The result of loading QuickJs bytecode. Either a function or a module.
- A value that can be (de)serialized to/from the quickjs runtime.
- Error during value conversion.
Traits
- The Callback trait is implemented for functions/closures that can be used as callbacks in the JS runtime.
